I'm a big fan of the new OWC Thunderbay Mini 4 with four 250GB Samsung SSD drives in Raid 1+0 for speed and reliability. You're looking at a good chunk of cash (~$900) but it's hard to beat! The advantage is that the enclosure comes with Soft Raid software and you can have multiple sets of disks.
An other favorite setup is a PCIe SSDs in an OWC Mercury Helios 2 chassis (PCIe enclosure) which is super fast and reliable and I typically pair it up with a Blackmagic Decklink duo card.
That's pretty good for a bus-powered drive but my issues with this kind of TB drive is that you lose one TB port and since it sounds like Jakguzik is on an older MBP, there might be no video output left.
The two setups I described in my previous post give you a TB pass through so you can still get video out of the same port.
To give you a sense of speed, here is what I get with three Samsung 850 EVO 250GB drive in Raid 0 in an OWC Thunderbay Mini 4 enclosure:
and here is what I get with a Sandisk Extreme 64GB USB 3.0 thumbdrive that cost $32.75 on Amazon:
You can now get the faster SanDisk Extreme PRO 128GB thumbdrive for $85 on amazon.
You can also get the new Samsung T1 Portable 500GB USB 3.0 External SSD for $220 and not lose a TB port.
